METHOD OF CONTROL OF SPACE VEHICLE TURN MANOEUVRE Russian patent published in 1997 - IPC

FIELD: space engineering; control of attitude of space vehicles and orbital stations. SUBSTANCE: space vehicle is turned over free motion trajectory and parameters over falling trajectory - vector and turn are automatically determined; to this end, control system uses iteration method, thus solving the boundary-value problem algorithmically: initial angular velocities are determined do that space vehicle should take final attitude from initial attitude due to uncontrolled rotation at preset time interval. After imparting calculated angular velocities to space vehicle, moment of transition to section of rotation of space vehicle about Euler's axis is determined such that fuel consumption for corrective turn is minimum and then respective efficiency function is continuously calculated in control system; corrective turn of space vehicle is effected at minimum magnitude of this efficiency function. EFFECT: low consumption of fuel, enhanced accuracy of turn at any unknown disturbances. 2 cl, 2 dwg
